CVE ID :CVE-2026-53371<\/p>\n

Description :In the Linux kernel, the following vulnerability has been resolved:<\/p>\n
RDMA\/ionic: bound node_desc sysfs read with %.64s<\/p>\n
node_desc[64] in struct ib_device is not guaranteed to be NUL-
\nterminated. The core IB sysfs handler uses “%.64s” for exactly this
\nreason (drivers\/infiniband\/core\/sysfs.c:1307), since node_desc_store()
\nperforms a raw memcpy of up to IB_DEVICE_NODE_DESC_MAX bytes with no NUL
\ntermination:<\/p>\n
memcpy(desc.node_desc, buf, min_t(int, count, IB_DEVICE_NODE_DESC_MAX));<\/p>\n
If exactly 64 bytes are written via the node_desc sysfs file, the array
\ncontains no NUL byte. The ionic hca_type_show() handler uses unbounded
\n“%s” and will read past the end of node_desc into adjacent fields of
\nstruct ib_device until it encounters a NUL.<\/p>\n
ionic supports IB_DEVICE_MODIFY_NODE_DESC, so this is triggerable by
\nuserspace.<\/p>\n
Match the core handler and bound the format specifier.<\/p>\n
Severity: 0.0 | NA<\/p>\n
